Abstract
Based on numerical simulation, the flow distributions of the ordinary header and three improved headers was studied with PIV, and a series of velocity streamline graphs of different cross sections were obtained. At Re=6.22×104 the outlet flow distributions of the ordinary header and an improved header, and the effects of flow distribution of three improved headers with different middle-hole-area ratios were compared. The experimental results showed that the perforated plate header configuration could effectively improve the uniformity of fluid flow distribution. Flow maldistribution parameter SU and the ratio of the maximum velocity to the minimum velocity θU of the type C header configuration were minimum. There was an optimum point between flow distribution and the middle-hole-area ratio.
